Title: Quick-freezing method
Inventor: FURUBAYASHI YASUO
IPC: F25D17/04
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent a cooling device from being frosted by a method wherein the cooling device is vertically installed at one side wall in a refrigerator chamber sealingly closed by a thermal insulated box to form a cooling chamber, fans are arranged at a front surface of the cooling device, a space at a front part of it is applied as a freezing chamber, cold air cooled by the cooling device is pushed out toward the front surface under a natural convection and fed into the freezing chamber by the fans. SOLUTION: This quick-freezing method is carried out such that circulating air flow from a freezing chamber 20 is not positively fed into a cooling device 16, but sucked by fans 22 arranged at a front surface of a cooling chamber, blown out again into the freezing chamber 20, cold air cooled by the cooling device 16 flows to a lower front side of the cooling device under a natural convection flow, its corresponding hot air flows into the upper part of the cooling chamber under a natural convection and entirely cooling operation is carried out through natural convection.  Since the natural convection shows a slow air flow, even if the hot air enters the upper part of the cooling chamber, the air is rapidly cooled with the cold air around the cooling device, resulting in that hot air containing moisture therein is prevented from being directly contacted with the cooling device and frosting is hardly adhered.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: SHIBATA NORIO
IPC: F02D41/14
Filed: 1986-12-18
Abstract: PURPOSE:To prevent an air-fuel ratio from being excessively thinned, by a method wherein during cold down, acceleration, or thinning of an air-fuel ratio, the upper limit value of an air bleed amount is reduced. CONSTITUTION:An air bleed amount control valve 7 is mounted to a carburetter 1, and control is effected by means of a control circuit 8. Singlas from various sensors 9-13 are inputted to the control circuit 8, and upper and lower limit values Imin and Imax1 of an air bleed amount are set by means of a first guard circuit 83. When it is detected that an engine is in a cold down state, on acceleration state, or a thinned state of an air fuel ratio, a second guard circuit 84 is actuated, and the upper limit value is set to Imax2 lower than the Imax1. This constitution enables prevention of an air-fuel ratio from being excesively thinned during cold down.

Title: Refrigerator
Inventor: HIRAOKA SEIJI
IPC: F25B1/00
Filed: 1988-11-30
Abstract: PURPOSE:To always ensure a constant oil quantity by providing a detector for judging the presence of oil in a compressor, opening for a set time a solenoid valve to an opposite side to the compressor whose oil level is lowed below the normal level, moving the oil of the other compressor, and making the height of the oil level of each compressor uniform. CONSTITUTION:In the case where the oil quantities of two compressors 1a, 1b are unbalanced, for instance, the oil of the compressor 1a is moved to the side of the compressor 1b and lowers down to the position of an oil level detector 9a, the contact is closed by the reaction of the oil level detector 9a to open a solenoid valve 7b, and the oil stored more than necessary in the side of the compressor 1b is introduced in an intermediate pressure chamber section of the compressor 1a through an oil equalization pipe 6b to return in the chamber. In addition, the solenoid valve 7b is closed by a timer after constant time elapses and a series of operation is completed. In the case where the oil quantity of the compressor 1b reduces, the same operation is performed and the oil is returned from the compressor 1a to the compressor 1b. Since the position of oil taking-out of the oil equalization pipe is set on the upper end of the proper oil level, the supply oil is not moved more than the compressor needs. Each compressor supplies oil each other and even if the oil quantity of either compressor is lacking a constant oil quantity is always ensured.
